Determining the magnitude and direction of land cover changes in the semi-natural areas of Haskovo Region, Southeast Bulgaria

Remote Sensing (RS) Data is widely used in the process of determining land cover change. In the present study, Tasseled Cap Transform (TCT), and modified Change Vector Analysis (mCVA) techniques were applied to Landsat 5 TM and Landsat 7 ETM data in order to be determined the magnitude and direction of land cover changes in the semi-natural areas of Haskovo Region, Southeast Bulgaria. It has been found that the magnitude of those changes increases by up to 50% in some of the territories under investigation.
